Fire Resisting Rolling Shutters & Doors

NoteRemovable guides, bottom rubber seals, brush seals, safety edges and wicket gates cannot be fitted to fire shutters.

Fire Shutters over fire exits and escape routesAppendix B of the Buildings Regulations Approved Document B states that roller shutters across a means of escapeshould only be released by a heat sensor, such as a fusible link or electric heat detector, in the immediate vicinity of thedoor. Closure of shutters in such locations should not be initiated by smoke detectors or a fire alarm system, unless theshutter is also intended to partially descend to form part of a boundary to a smoke reservoir.

Fire Resisting Rolling ShuttersWhat is a fire resisting rolling shutter?

A traditional single skin fire resisting rolling shutter looks and operates in a similar way to a standard steel rolling shutter.The physical differences are that the materials used are heavier and there are more fixings required. Syston Doors can also

provide alternative physical fire shutter products as shown in this brochure.

Fire Shutter Structural RecommendationsThe structure supporting the rolling shutter must be a fire resistant separating element (to BS476, Part 20, 21, 22, 1987),

having a fire resistance equal or greater than that required of the rolling shutter itself and must be capable of supporting therolling shutter for the required fire resistance period without compromising the fire performance of the rolling shutter.

Consideration must be given to the loads imposed by the various rolling shutter components, i.e. end plates and the barrelsupport brackets.

Fixing to Masonry Openings.Opening to be constructed from masonry, reinforced concrete or dense concrete blocks (7 Nm and above) and have a fireresistance equal or greater to that of the door.

Lightweight and hollow blocks are NOT suitable.

All concrete/masonry elements must be designed in accordance with BS5628: Part 3:1985 and have a density of > 600kg/m3.Lintels spanning the structural opening should comply with BS8810: Part 1:1997.

Client to ensure that openings are plumb and square and that the structure will accept rawlbolt type fixings without cracking.

Subject to the fire shutter being fitted to a flat surface, gaps of up to 6mm are acceptable (for a distance of 150mm), but if, due toan uneven structural finish, larger gaps are apparent, they must be sealed with a suitable fire retardant material, e.g. plaster, fireretardant mastic seal (non-intumescent). Syston Doors do not include this sealing.

Fixing to Steel OpeningsWhere fire resisting rolling shutters are fitted to steel, the steel must be insulated and thermal bridging effects considered whereinsulation has been breached.

It is recommended that a critical steel temperature of 4000C and steel sections with an Hp/A below 230m-1 are used for designing

fire resisting steel supporting structures.

Fixing to Timber PartitionsFire resisting rolling shutters can be fixed to non-loadbearing timber framed or steel framed partitions (with suitable timber inserts all round)up to 2750mm wide x 3250mm high, (maximum area 10m2), for up to 60 minutes under cover of BRE test certificate FG 7941 N.The opening must be capable of carrying the weight of the shutter and be equal or greater than the fire resistance of the rollingshutter assembly.

It is most important that the Contractor adheres to the opening construction details, as these are alsocovered by the assessment and as such become the CONTRACTOR’S RESPONSIBILITY.

Fire testingWe do not as standard include for a return journey involving a fire test after the original installation. We can include this at extra cost.

MaintenancePlease note that it is a requirement under Regulatory Reform (Fire Safety) Order 2005, that fire resisting Rolling Shutters aretested every six months. Full width access should therefore be maintained to the shutter to enable this to be carried out.Syston Doors can offer routine testing and maintenance contracts on application. If no contract is entered into we cannottake any responsibility for the working condition of the shutters after the guarantee period.

‘Flame Shield 120’ Tubular Motor Operated Fire ShutterApplication‘Flameshield 120’ 240v single phase tubular motor operated fire shutters provide an attractive and space friendly fire shutter solution with a fire resistanceas standard of up to 120 minutes (2 hours) and for openings up to 4800mm wide x 1900mm high (see size grid).

The shutter is constructed to Warrington Fire Research Centre WARRES No. 145904, the test is in accordance with clause 8 of BS476 Part 22.

The attractive 50mm flat faced lath for openings up to 3500mm wide x 2500mm high, make it most suitable for servery type openings or where aestheticappearance is important.

Over this size a traditional 76mm curved lath is used, but still offers the benefits of a space friendly coil casing and guide detail.

General SpecificationCurtainShutter curtains are constructed from 50mm flat faced laths up to 3500mm wide x 2500mm high or 76mm traditional curved laths over this size, with astandard Tee bottom rail. (If smaller openings are adjacent to larger openings the laths on the smaller openings would normally be 76mm to ensure allmatch).

Hood (Coil Casing)A profiled galvanised sheet steel hood is included as standard. A fascia can be included at extra cost on fit within applications.

Dependent on the fire rating of the shutter and the size of the opening, the shutter could require a hood support bracket.

Manual override by hand crank can be included at extra cost.

Available Modes of ActivationFusible Link releaseOn activation of the fusible link from a local heat source of 68˚C, this will send a signal to the relay which will signal the shutter to power down fromthe maintained supply or alternatively from the optional battery back up unit.

Fire Alarm linkBy use of a fire alarm relay the shutter will close under power. The unit will require a maintained supply or alternatively we can supply with aBattery Back Up unit.

Volt free fire alarm signal required.

Syston Doors do not include for connecting into the fire alarm system.

Audio Visual Warning ClosureFor use when an audio & visual warning is required of the shutter closing. The unit also includes a facility for a delayed closing of the shutter.The fire alarm signal is connected directly into this unit. On activation from the fire alarm the unit starts to flash & sound with the shutterclosing after a pre-determined delay (10 - 240 seconds).

Type of OperationHand ChainAvailable up to 4000mm wide x 4000mm and suitable for applicationswhere the shutter is held open, closing only in the event of a fire. Manualclosing is achieved by releasing a pull cord, which allows a controlleddescent via a gear unit at approximately 100mm/second.

Operating by the hand chain is a slow process and power operation isrecommended when everyday use is required.

ElectricSuitable for all sizes of shutter, the motor is either single phase (240 Volt50 Hz) or 3 phase (415 Volt 50 Hz) dependant on size of door.

A controlled descent of 100mm per second (approx.) is an inbuilt safety feature.

In the event of power failure, manual override is achieved by pulling a pullcord to close the shutter under controlled descent and a hand chain to open.

The handchain override is designed for emergency use only.

As standard each shutter will include an open/stop/close push buttonstation mounted on the motor side at approximately 1500mm above thefinished floor allowing sight of the shutter during normal operation.

Other control options available are shown under ‘Options’.

All switchgear unless otherwise stated are surface mounted.

Modes of ActivationOption 1Self closing by means of a thermal fusible link activated at a temperatureof 68˚C and mounted to the underside of the hood

Option2*24v DC auto resetting solenoid release device connected to the firealarm/smoke detector.

Solenoid automatically resets when the shutter is fully opened bypressing the ‘up’ button and when the alarm has been turned off.

(On hand chain operated shutters the solenoid is reset manually by pulling on a cable).

Syston Doors do NOT include for connecting into the fire alarm.

The fire alarm circuit must provide the supply for the solenoid (0.5 amps) withan initial supply of 3.5 amps for 20 – 30 m/seconds to release the shutter butonly when in the alarm condition. (If the fire alarm circuit is unable to providea 24v DC supply for the solenoid or ancillaries a battery back-up system canbe provided at extra cost).

Option 3All as Option 2 but with mechanical fusiblelink back up.

‘Fireflex R’ Radiant HeatReducing Fire Resisting Rolling ShutterApplicationTested by the Loss Prevention Council (Test Report 220737) to an integrity of 240 minutes (4 hours) for openings up to 50 m2

Fireflex is an obvious choice where increased risk of fire is a major concern. Fireflex provides a substantial safety barrier between the sourceof the fire and any precious or dangerously flammable stock. Fireflex is the perfect application for hospitals, shopping centres and industry.

Designed for internal or external applications where increased fire protection is required. It provides radiant heat protection with reliableoperation through a simple control panel that can be adapted for a range of activation methods.

Fireflex is power operated with controlled descent following automatic activation. A safety brake is included as standard at the non motor end.

Due to its unique construction, the radiant heat levels around Fireflex drop from 65kw m2 to 2.7 kw m2. This means that combustiblematerials can be stored 500mm away from a 1200oC inferno, increasing floor space and reducing risk and break down of firecompartmentation.

Fireflex R also has a weighted sound reduction of 18 dB (BS5821 Part 3: 1984).

General SpecificationCurtainManufactured from pre galvanised material designed to provide a hollow section panel with ceramic infill. Each section is100mm high with twin ribbed face for rigidity.

The curtain is held in position with purposely designed end fittings which act as a curtain alignment system. The bottom panelis terminated with a galvanised steel plate with horizontal and vertical slots.

Hood (Coil Casing)All Fireflex R shutters include a galvanised sheet hood as standard with optional motor cover. (Motor cover always includedif less than 2500mm high).

GuidesFormed from pre galvanised steel.

EndplatesMild steel of appropriate thickness relative to door size.

FinishStandard finish to all parts is galvanised.

Powder coated finish to a standard range of BS/RAL colours available at extra cost

OperationFireflex Shutters are power operated by a 3 phase & neutral motor withvarious options of release:

Level 1 Fusible Link OperationNormal operation by push button station or keyswitch with fuse link toclose shutter at local heat source of 75

oC.

*Level 2 Alarm activation with manual resetNormal operation by push button station or keyswitch with solenoidrelease to close shutter following fire alarm signal with manual reset ofsolenoid by pull cables.

*Level 3 Alarm activation with automatic resetNormal operation by push button station or keyswitch with solenoidrelease to close shutter following fire alarm signal with automatic resetof solenoid once alarm is switched off by fully opening shutter.

*Level 4 Alarm activation with automatic reset and part close facility Normal operation by push button station or keyswitch with solenoidrelease to close shutter following fire alarm signal with automatic resetof solenoid once alarm is switched off by fully opening shutter.

Shutter can also part close to act as a smoke curtain, fully closing afteran adjustable delay. Shutter must have maintained supply for thisfunction.

*For Level 2, 3 and 4 Audible Visual (with adjustable delay timer) can be includedto one or both sides of the opening.

Fire Alarm requirementsThe Fire Alarm circuit must provide the supply for the 24v DC solenoid(0.5 amps) with an initial supply of 3.5 amps for 20-30 m/seconds torelease the shutter but only when in the alarm condition.

If the fire alarm is unable to provide a 24v DC supply a battery back upsystem is available at extra cost.

The 24v DC supply needs to be provided separately from that of the firealarm system as under the requirements of BS5839 Clause 19, theconnection of such equipment is specifically prohibited.

Syston Doors DO NOT include for connecting into the fire alarm circuit.

Note! To comply with current legislation fire shutters cannot be linked to fire alarmsystems if they are over fire exits or are on a fire exit route. They can only be fittedwith a device, which will close the shutter, by a local heat source i.e. fusible link.
